| Cryptographic key sovereignty (CKS) | Key management with a European vendor | 40 |

Why digital sovereignty matters with DataGalaxy
DataGalaxy is headquartered in FR and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.
Data is hosted exclusively in the EU, so DataGalaxy scores best on data residency.
DataGalaxy is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.
What this means for your organisation depends on your whole stack and context. The free assessment weighs DataGalaxy together with your other vendors and gives a total score, a heatmap and the main risk drivers.
